In mathematics, a percentage (from Latin per centum "by a hundred") is a number or ratio expressed as a fraction of 100.
Answer:
1: 130
2: 70
Step-by-step explanation:
Supplementary angles add up to equal 180
So to find the measure of the missing angles, we subtract the measure of the known angles from 180
For #1
∠B = 180 - 50
180 - 50 = 130
Hence ∠B = 130
For#2
∠D = 180 - 110
180 - 110 = 70
Hence, ∠D = 70
